Around here for customer supplied big block MOPAR iron heads.......when we quit doing them. Depending upon the quality of parts used. Cleaning the heads, valves 2.14-2.20/1.81, springs, retainers, locks, seals, valve guides, hard exhaust seats, milling = approximately $830-$1,415.

Plus the valve job & porting to the level of flow you want! $700-$2,000
